44a - Fuel pump - GHN3-101 to 44438 (to 1964) Negative / Positive earth AZX1331
Original SU Pump. This pump is dual polarity which means it can be used on original positive earth cars or those that have been converted to negative earth. It retains the original mechanical points that were fitted by the factory. As it is a dual polarity unit, it supersedes the standard AZX1332 positive earth pump. If you want the more reliable electronic points version you will need to order either AZX1332EP (electronic/positive earth) or AZX1331EN (electronic/negative earth) See below.
